Some characters are corrupted (with possible fix)

[yalfg]

The selected unicode character is inserted using xdotool, but xdotool may corrupt some characters (this is ackowledged in its man page, see BUGS section). I also tried xte, from the xautomation package. No more corruption, but then xte silently fails if the Unicode character is not part of the current keymap... In the end I found this trick that works for me (so far):

     echo -n "$selected_symbol" | xclip -i
     xdotool click 2

The first line put the selected Unicode character in the primary selection clipboard using xclip. The second line insert a middle click, pasting the selection in the current window. This way the complexity of going from a character to X keyboard events is not needed, it's just like a cut and paste.

This works on X11, not tested under Wayland (is middle click paste supported now?). So it may be X11 only, TBC.
